Application May 24, 1933, Serial No. 672,711

1 Claim. (CI. 81-31) This invention relates to jar clamps and itsgeneral object is to provide a clamping tool that is primarily designedfor association with Mason jars and the like for applying and removingthe caps thereof as well as for lifting, carrying and handling the jarsin moving them from place to place when hot or otherwise difficult tohandle, without fear of injury to the person or damage to the jars orcaps thereof.

Another object of the invention is to provide a jar clamp that includesprotecting and gripping means that is thickened or increased whereneeded, in order to prolong the life of the device and to facilitate theeasy and convenient operation thereof.

A further object of the invention is to provide a jar clamp of thecharacter set forth, that is simple in construction, inexpensive tomanufacture, easy to use and extremely efficient in operation andservice.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of one form of our clamp.

Figure 2 is a side view showing the same in use.

Figure 3 is an end view thereof.

Figure 4 is a view of a modified form with parts in section andillustrates the application of the clamp to a jar when lifting, carryingor otherwise handling the same.

Figure 5 is a similar view of a further modified form.

Figure 6 is an end view of the form as shown in Figure 5, with partsbroken away.

Referring to the drawing in detail, and particularly to Figures 1 to 3inclusive, it will be noted that our jar clamp may include a frame whichis formed from a single piece of resilient wire or other material havingsuilicient resiliency to perform the intended functions.

The frame is bent to provide handles 1 which are normally disposed indiverging relation with respect to each other, as clearly shown inFigure 1, and formed inwardly of the handles are curved portions 2 for apurpose which will be later described, and the curved portions haveformed thereon substantially semi-circular portions 3 which have theirinner ends spaced and terminate into a coil 4 to add to the resiliencyof the device as will be apparent.

The outer ends of the handles 1 have formed thereon arms 5 which aredisposed at right angles with respect thereto and are slightly curvedupon themselves as best shown in Figure 3.

The handles 1, curved portions 2, and the major parts of thesemi-circular portions are covered with a tubing 6 which may be formedfrom rubber or a composition containing the same in order to set up agripping action as will be apparent. The parts of the covering or tubing6 that receive the semi-circular portions and the curved portions arethickened as clearly shown in Figure l, to compensate for wear as wellas to increase the gripping qualities, as it will be obvious that thesemi-circular portions as well as the curved portions are adapted togrip jars and caps in applying and removing the caps.

In Figure 4 we have illustrated a slightly modified form in which thesubstantially semi-circular portions have their inner ends slightlyinclined and disposed to cross each other and terminate in a coil 9.

In the modified form of Figures 5 and 6, it will be noted that thesemi-circular portions which for distinction are indicated by thereference numeral 10 are pivotally connected with each other and forthat purpose the inner end of one semicircular portion is bifurcated,while the inner end of the other semi-circular portion is reduced as at11 to be received between the ears 12 of the bifurcation, with the pivotpin 13 extending through the ears and reduced portion as clearly shownin Figure 6.

From the above description and disclosure of the drawing, it will beobvious that we have provided a jar clamp that may be used singly or inpairs when applying or removing the caps of jars, and while we haveshown the semicircular portions which are of course jaws applied to thecap of a jar, the semi-circular portions or jaws of another clamp may beapplied to the neck of the jar so that an ample purchase may be hadthereon. The curved portions 2 also act in the capacity of jaws for useon smaller jars and their caps.

In lifting, carrying or otherwise handling the jars, the arms 5 comeinto use and are applied about the neck of a jaw as clearly shown inFigure 4. The covering or tubing 6 is used in all forms of the inventionand extends about the arms 5 so that an ample gripping surface will beprovided, as will be apparent.

wire and including handles, outwardly curved portions formed on saidhandles, semi-circular portions formed on the outwardly curved portions,said outwardly curved portions and semicircular portions providingclamping jaws, said semi-circular portions having their inner endscrossed, a coil formed with the crossed ends to add to the resiliency oithe frame, an elastic covering for said tool and disposed on the majorportion thereof, and said covering being thickened where disposed aboutthe jaws.
